本発明は機械を弾性支持するための弾性支持要素に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resilient support element for resiliently supporting a machine.
機械を据えつける際、多くの場合弾性支持体を設ける。When installing the machine, elastic supports are often provided.
支持体の弾性要素はゴムあるいはネオプレンで構成され
るか、あるいはバネ鋼のバネ系で作られる。弾性支持要

支持され静的に未定に置かれた基礎が静的にほぼ一定の
システムに移される。弾性支持によシ制約が減シ、旧Ｄ
ＩＮ４０２４ （１９５５年１月）により必要となって
いた曲げ強さのある基礎に比べてより容易、より経済的
な基礎の施工が可能になる。The elastic elements of the support are composed of rubber or neoprene or made of a spring system of spring steel. The transmission of vibrations is reduced by the elastic support elements, and at the same time the statically indeterminate foundation, supported in several places, is transferred to a statically almost constant system. Elastic support reduces constraints, old D
This makes it easier and more economical to construct foundations than the bending-strength foundations required by IN4024 (January 1955).
弾性支持体は、特に多くの軸受と貫通した軸けん引ロー
プを有する横長あるいは大型の機械８例えばタービン発
電機の場合には、従来弾性支持体を用いるのが一般的で
あった。その場合。Elastic supports have conventionally been commonly used, particularly in the case of oblong or large machines 8, such as turbine generators, which have many bearings and shaft traction ropes passing through them. In that case.
現在では基礎の建設の前に予測される運転荷重に関する
基礎の弾性曲線に対応させて弾性要素に予圧を与える。Nowadays, before the construction of the foundation, the elastic elements are preloaded in accordance with the elastic curve of the foundation with respect to the predicted operating loads.
機械が組立てられている間に。while the machine is being assembled.
基礎に間隔薄板を用いて、あるいは油圧ピストンと遮断
ラムによって調整張力がかけられる。Adjustable tension is applied to the foundation using spacing plates or by hydraulic pistons and shutoff rams.
作動中の軸けん引ロープを調節するために従来は、特に
自動的に作動し動作に附随する調節方法として基礎の調
整引張けなされなかった。In order to adjust the axial tow rope during operation, it has not been possible to use basic adjustment tensioning, especially as an automatically activated and movement-accompanied adjustment method.
弾性要素の支持力は相対的に長い変形行程に比例する。The supporting force of the elastic element is proportional to the relatively long deformation stroke.
一方９機械基礎の硬性は実際には支持要素のそれよりも
大きいと考えられる。On the other hand, the stiffness of the 9 machine foundation is actually considered to be greater than that of the supporting elements.
本発明はかかる特性を弾性要素の負荷の変化（を通じて
軸けん引ロープの調節のために利用する。その場合長い
調節行程を通じて弾性要素のところで基礎変形を最小に
できる。The invention exploits such properties for the adjustment of an axial traction rope through a change in the load of the elastic element, in which case basic deformations at the elastic element can be minimized over long adjustment strokes.

作用する。This is done in accordance with the invention in the manner specified in the features of the main claim. In this way it is possible to vary the height or prestress of the support element and, from there, to vary the load. In addition, the support conditions change and influence the adjustment of the tow rope of the bending-elastic base through a correspondingly changed elastic curve.
付加的な調節装置として油圧機構を必ずしも常に用いる
ことができない場合には１弾性要素に調整可能な遮断機
構を設置し、有効に利用せねばならない。最も簡単な方
法としてはネジあるいはくさびで構成することができる
。If a hydraulic mechanism cannot always be used as an additional adjustment device, an adjustable cut-off mechanism must be installed on one elastic element and used effectively. The simplest method is to use screws or wedges.

のち緊密 □な結合を復原させる。You can always make adjustments even while driving. In order to remotely control such strokes, the adjusting device can be equipped with a remotely controllable operating mechanism 1, for example a hydraulic or electromagnetic device. This makes it possible to release the tight coupling, adjust the axle traction rope, change the preload of the cut-off mechanism □, and then restore the tight coupling.

度は測定方式の精度によって決まる。The additional installation of a shut-off mechanism and one status indicator for the elastic element on the elastic element provides all the characteristics necessary for automatic adjustment of the shaft traction rope. By carrying out the calculation steps 9, for example in a microprocessor, automatic optimization of the adjustment conditions is possible. Its accuracy depends on the precision of the measurement method.

そののち機械ケーシングのところで自動的になされる。The industrial significance of elastic elements designed in this way is
This becomes especially obvious when installing a turbine generator at a power plant. In addition to the advantages in terms of the cost of foundation construction9, for example, the maintenance intervals during the operation of the plant are substantially determined by the quiet operation or shaft adjustment of the turbine. For maintenance inspections, the equipment must be disconnected from the power system and the turbine generator must be shut down. Adjustment of the axle traction lobe is then made automatically at the machine casing.
調節装置を備えた弾性要素を導入すると保守点検間隔が
著しく延びるだけではなく同時に運転再開時に必ず生じ
て調節状態を変える勢膨張が調整される。摩耗の低減も
その他の長所とともに期待される。The introduction of an elastic element with an adjustment device not only significantly extends the maintenance interval, but also at the same time adjusts the force expansion that always occurs upon restart and changes the adjustment state. Reduced wear is also expected, among other benefits.
本発明の概要は以下の通りである。The outline of the present invention is as follows.
複数の軸出と貫通した軸けん引ロープをもつ。It has multiple shaft extensions and a penetrating shaft traction rope.
横長ないし大型の機械を弾性支持するために。For elastically supporting horizontally long or large machines.

行程を通じて基礎変形を相対的に小さくできる。This method allows relatively small basic deformations to be achieved through a relatively long adjustment stroke at one elastic support element for adjusting or readjusting the axial traction rope.
次に本発明の具体例を図面によって詳細に説明する。Next, specific examples of the present invention will be explained in detail with reference to the drawings.

られており、それは基台２の上に置かれている。A turbine generator 1 is installed on a base 2. In order to provide elastic support for the turbine 1, a generally bendingly elastic base 2 rests on known elastic springs 3. The shaft traction rope 5 of the turbine 1 is supported in a bearing pedestal 6, which rests on the base 2.

Thereafter, the base 2 is tensioned in a known manner so that completely silent operation of the shaft traction rope 5 can be expected during operation. Thereafter, no adjustment tension is applied during operation, and the necessary adjustments at 9 o'clock are made by adjusting the bearing pedestal 6 when the tamping machine is stopped during maintenance and inspection.

に強い結合をもたらす。The spring 3 is fitted with a special adjustment device 7 according to the invention. It remains in that part continuously and changes the support conditions of the axial traction rope 5 through changes in the load of the spring 3. As can be seen in FIG. 3, the hydraulic adjustment device 7 is mounted on the spring casing 8 in such a way that the load on the spring 3 changes in the same way during its operation. The screw 9 has the function of applying preload before assembly. The liner 10 provides a trouble-free and particularly slip-resistant connection between the spring 3 and the base 2 or base support 4.

A tight connection between the spring 3 and the base 2 is achieved using adjustable wedge connections 11, 12 through all adjustment areas. This is clear from FIG. Spring casing 8
The wedge plate 11 which is tightened on top serves as the slope of the wedge 12.

７の荷重が除かれる。The wedge connections 11,12 are readjustable and released when the adjusting device 7 is actuated. The adjustment cylinder 13 makes the necessary adjustments to the wedge 12 of the wedge connection, which serves as a blocking mechanism. The wedge then supports the base and the load on the adjustment device 7 is thereby relieved.
